The tank has been set up for 3 years I have a koran angel, 2 damsels, 2 clowns, and a solar wrasse. I added the yellow tang, Koran Angel, 2 clowns and 2 damsels when i upgraded my 55 gallon to a 125 gallon tank 3 years ago. They have all been doing fine besides my fox face i added about a month ago and it died about a week ago but i took it out and it had no signs of ich. The solar wrasse was added when I added the foxface. The solar wrasse is doing great. I feed them a variety and I feed them once a day. I feed them flake food, mysis shrimp, and brine. my ph is 8.2 alkalinity is 7 ammonia is near 0 nitrates are near 0 phosphates are areound .13 calcium is 400.
